The short answer
Chaddleworth lies below the southern slopes of the Berkshire Downs, where little stands between the wind and the roof edges. Those edges take the strain, so loosened tiles, failed bedding and lifted flashings tend to start there.
Chaddleworth sits just east of the A338, under the southern slopes of the Berkshire Downs, within the North Wessex Downs National Landscape. It is a quiet place, and an open one. Wind arriving across downland meets the roof edges first.
Q1.1Why do ridges and verges lift under the downs?
The ridge is the top line where two slopes meet, and the verge is the roof's rafter-line edge at a gable wall. Both are normally bedded in mortar. With age the mortar cracks and crumbles, and a tile with no bedding left under it can lift in a single gust. Under BS 5534:2014, ridge and hip tiles also receive mechanical fixings, so mortar is no longer the only thing holding them. On an exposed roof, that second fixing is worth having, and we describe the choices on our ridge, verge and dry-fix page.
Q1.2What do wind-driven rain and gutters do to eaves?
Eaves are where wind-driven rain is pushed under the lowest tiles. Gutters overloaded with leaves then spill down the wall and the fascia behind them softens. Chimneys stand out in the wind more than any other part of the building, so their pointing, flaunching (the mortar cap that seats the pots) and lead flashings receive a hard time. Our chimney repairs page explains the work in detail.
After a storm, a glance at the roof from the lane, binoculars in hand if you own a pair, can show a slipped tile or a gap in the ridge. Send a photograph our way and we will talk through the next step. If water is coming in, a leak gets our attention ahead of routine jobs, and the first aim is a dry, safe roof.
Wear in an exposed place is no mystery, and it is manageable. Keep the edges fixed, keep water moving off the roof, and keep an eye on the chimney. Between them, those three habits account for a great many of the repairs we are asked to do. A short annual look, or a survey every few years on an older roof, is the sensible way to catch the next problem while it is still small.
